For feverish patients, ice can be applied to the forehead or armpits of the patient with a waterproof cloth or a dry towel wrapped in ice. Attention should be paid to changing the cold compress after a period of time to prevent frostbite from occurring in one area for a long time. In addition, it is necessary to observe whether the ice melts during the cold compressing process to prevent the liquid from wetting the patient’s clothing and bedding. If this happens, the clothing and bed sheets need to be changed in time to prevent the patient from getting cold again. At the same time, the body temperature should be closely monitored during the cold compressing process, and the temperature measurement should be avoided at the cold compressing site to affect the interpretation of the test results.
